Ayasofya, also known in English as Hagia Sophia, rises over the historic peninsula of Istanbul with a vast central dome that has dominated the skyline since the sixth century. Completed in 537 under the Byzantine emperor Justinian I as the cathedral of Constantinople, it later became an imperial Ottoman mosque and now functions again as a mosque while remaining a major historic monument.

The mixture of stone structure, plastered surfaces and mosaic decoration gives the space a layered appearance, with Christian iconography from the Byzantine period sharing the same volume as later Ottoman elements such as painted calligraphy panels.
From Byzantine cathedral to Ottoman mosque
Ayasofya’s current form reflects a succession of religious uses that can be traced in the fabric of the building. It served as the cathedral of Constantinople for centuries, with its dedication as a Byzantine church in 537 and its status as an Eastern Orthodox cathedral maintained until the Ottoman conquest in 1453.Eastern Roman Church in Istanbul After the capture of the city by Sultan Mehmed II in 1453, Ayasofya was converted into an imperial mosque and remained a major Ottoman place of worship.mosque in 1453
